Research
The lab works on robust, identifiable and interpretable machine learning tools for scientific inference. We work on both core machine learning topics and the application of machine learning algorithms for scientific inference in the life sciences. Our research focus is on:
- Computational statistics for dynamical systems
- Representation learning, especially using contrastive learning and generative pre-training
- Hierarchical and compositional representation learning
- Identifiability and robustness of machine learning algorithms
- Applications to systems neuroscience and biology
The following is a list of key publications within these focus areas. For a full list of publications, see the research section or Google Scholar.
